[QUOTE="WayneF, post: 214138, member: 12496"] That card does seem faster than I imagined a Class 10 card could be. Here is a reputable memory card speed test, this in a D7000 camera. [URL="http://www.robgalbraith.com/camera_wb_multi_page3c04.html?cid=6007-12454&sort_col=raw&sort_dir=DESC"]Rob Galbraith DPI: Nikon D7000[/URL] Says Transcend UHS-1 can write 21 MB/second (in a D7000 - cameras models have different processors and vary in speed). Whereas Class 10 means the slowest of read or write is at least 10 MB/second, which is always write. The D800 is also there, but I don't know how it compares to D600. Certainly 21 MB is at least 10, but the faster cards typically don't mention Class. Anyway, if the card write speed is 21 MB, and if your JPG file is 12 MB, then it takes 12/21 = 0.57 second to write one file. I doubt a faster card would show much difference. [/QUOTE]
